It's a bit more complicated than that...
It really isn't that difficult, and certainly not beyond the wit of anyone here to understand. And the graph really helps- it shows that rotational velocity is pretty constant except when planets are close to their sun, when it can get really fast. Which is also what the words say.
There are two surprising things. First, that we've discovered loads of exoplanets - the first one was discovered pretty recently, and second that we're able to measure things about them pretty accurately.
